A very happy birthday to artist Ellsworth Kelly, who is turning 90 years today.As a freshman art student, I was shown this drawing by my professor, John Clovis. He urged me to note it's simplicity and confidence of line, saying something to the effect of, "When you draw a line, have faith in it - really draw a line." I was enthralled with Kelly's drawing and resolved to strive for a similar confidence and simplicity of composition.
